Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a dry-field direct seeding device for paddy fields.

[0002]

2. Description of the Related Art Conventionally, a technique related to a dry rice direct seeding device has been known. However, in Japan, direct seeding of rice in dry rice fields is actually carried out only in some areas, and the method of raising seedling mats and transplanting them with a rice transplanter is still the most popular. However, in the method of raising seedling mats and transplanting them with a rice transplanter, a large area and high density management are required for raising seedling mats, and the time of rice planting is limited, so one farmer can plant rice. The size of the paddy fields was limited, making it impossible for Japan to grow agriculture.

[0003]

DISCLOSURE OF THE INVENTION The present invention eliminates the above-mentioned problems and eliminates the need for growing seedling mats and transplanting with a rice transplanter in order to increase the size of a paddy field that can be cultivated by one farmer. The present invention provides a fertilizing and sowing device. The main reason why the direct sowing method has not spread nationwide so far is that when sowing with a fertilizer sowing device, many seeds are unable to germinate because the sowing depth of seed paddy is not constant, and transplanting by rice transplanters. This is because there was a higher possibility of stock-out than in the case of. In order to solve such a problem of the conventional direct seeding of dry rice, the present invention ensures a constant seeding depth and reduces the rate of missing seeds of direct dry seeding.

[0004]

The problems to be solved by the present invention are as described above. Next, the means for solving the problems will be described. That is, in a fertilizing and sowing apparatus that performs fertilization and sowing at the same time, the front roller 2 is arranged in the bearing at the front end, and the rear roller 1 is arranged in the bearing at the rear end, and the front roller 2 and the rear roller 1 are arranged.
On the line connecting the two, the seeding groove double disks 5L and 5R are arranged at positions between the two, and the fertilizing groove disk plate 3R arranged in parallel to the traveling direction is fixed to the side of the front roller 2. A fertilization-grooving double disc is supported by bearings on the fertilization-grooving disc plate 3R, which is inclined in the traveling direction, on the side of the fertilization-grooving disc plate 3R.

Further, in the fertilizing and sowing apparatus, the fertilizing and producing grooved disc plate 3L attached to the side of the fertilizing and producing grooved disc plate 3R.
The fertilization depth can be changed by changing to the one having a different diameter c.

[0006]

[Operation] Next, the operation will be described. In the present invention, the sowing depth h is made accurate by making the unevenness of the field scene even so that the field scene is a surface that is nearly horizontal. The front roller 2 is arranged at the front end and the rear roller 1 is arranged at the rear end, and the both sides of the roller are used to evenly check the reference field scene. Then, the rear roller 1 and the front roller 2 are leveled, and the fertilizer application groove double disc 3L is moved from the position as the reference field scene.
・ 3R is made to penetrate into soil to a certain depth. In FIG. 2, the fertilizer application groove double disc 3 is 3R.
3B bites into the depth e, and 3L bites into the depth g, resulting in a difference depth b between the two. However, in the part of the difference depth b, only the fertilization fertilization groove disc plate 3R bites and the fertilization fertilization groove disc plate 3L does not bite, so the groove is not completely formed, and the fertilizer has the difference depth b. Is not reached. Therefore, it is possible to change the depth b of difference and the seeding depth g by changing the fertilizer application grooved disc plate 3L to have different diameters c. The diameter of the fertilizer application grooved disc plate 3R is d.

The front roller 2 and the rear roller 1 establish a standard for the field scene, and the fertilizing and sowing device does not dive below the paddy field.
In this state, from the reference field scene, the seeding groove double disk 5
As shown in FIG. 6, L and 5R bite into the soil to a certain depth h to form a fertilization groove in the portion. Therefore, the rear roller 1 and the front roller 2 can be supported to even out the unevenness of the field scene, so that the depth h of the groove to be opened next by the seeding groove double disks 5L and 5R can be always constant. Further, since the inside of the rear roller 1 and the front roller 2 is hermetically sealed, it does not easily sink below the field scene even in soft soil.

The seeding depth h can be made uniform. By making the seeding depth constant in this way, it is possible to suppress the decrease in germination rate and the number of missing strains is small, so it is possible to spread direct seeding of dry rice fields. In addition, since the seeding depth h is constant, the seeds are maintained in the ground with a constant depth, so that even in the case of a cold wave or freezing, the seeds may be prevented from germinating. I no longer receive it.

As in claim 2, fertilizer application grooved disc plate 3R
Since the fertilization depth disc plate 3L attached to the side of the fertilizer is changed to have a different diameter, the fertilization depth can be changed.
Since the fertilization mechanism support rod 7 is moved up and down to change the fertilization depth, the fertilization groove disc plate 3L can be replaced even if the sowing depth is also changed.
The fertilization depth could be changed without changing the sowing depth. Further, if the fertilizing-grooved disc plate 3R is changed, the front roller 2 is attached, so that replacement is troublesome, but since the fertilized-groove disc plate 3L is only the disc plate, it can be easily changed. You can do it.
